by eliminating thenecessity of providing reinforcing frame work and driving penetrating posts, as shown in my said allowed application.

Another important object of my invention is the provision of novel means for mounting the slides or control gates proper on the body of the head and novel means for mounting the tail piece on the head, said means permitting adjustment of said tail piece relative to the head and allowing the convenient and quick association of the tail piece therewith.

A further important object of my invention is the provision of means whereby a pair of control slides or gates proper can be mounted in the head, whereby the pair of slides can be effectively manipulated accord ing to the height of the water in the ditch and the amount of water desired to Ho therefrom. r

A further important object of my inven tion is the provision of novel means for reinforcing the body of the head gate whereby the necessity of providing a reinforcing frame Will be eliminated.

A still further object of my invention is to provide an improved head gate embodying a minimum number of parts and which can be manufactured and placed upon the market at a low cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described,

claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a front elevation of my improved head gate.

Figure 2 is a rear elevation of my improved head gate- Figure 3 is a horizontal section through 1930. Serial no. 472,076.

the gate taken on the line 33 of Figure2 I looking in.the' direction of the arrows and illustrating the novel means for mounting the slides, or. gate proper and the tail piece on the heador body.

Figure 4 is a vertical central section through my improved headgate taken on the line 4-4 of Figure 2. I

' Figure 5 is a detail perspective view of'one connection with my device. H Figured is a detail perspective viewiof a single gate which. can be employedwith my device. Figure 7 is a rear elevation of a slightly ofthe pairs of. slides or gates proper used in modified form of my gate for use in connection with the piping, and V Figure 8 is a. central vertical section through the modified form of" my device taken on the line 88of Figure 7.

Referringto the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my improved headgate, which comprisesa body or head 10, preferably formed from a single sheet of metalofthe, desiredgage; .The side edgesof-the body can taper downward to ward the lower edge thereof as indicated by the reference character 11. i On opposite sides ofth'e verticalcenterof the plate adjacent to its side edges, the plate is reversely folded to provide parallel inner guides 12 andparallel outer guides 13 which are offset toxprovide shoulders 13" asshown a so clearly in Figure 3. These guides 12 and1'3.

has riveted or. otherwise secured thereto, an angle iron bar 14, which constitutes means a ing the plate. Theupper edge of the plate" a 1 for adding rigidity to theientire plate stru'c- I ture and also asmeans-for facilitatingtlie positioning of the plate in the ditch. In-order to provide further means for reinforcing the plate, the same can be'provided with vertically'disposed' struck out ribs 15, between the guides l2and 13 and the side edges of the plate and horizontal struck out ribs 16 beformed directly in the plate between the inner and outer guides 12 and 13 and the inner guides 12 slidably receive gate sections or upper and lower slides 18 and 19. The eX- treme upper edges of the slides or gate sections 18 and '19 are bent laterally 'to provide manipulating handles 20. As shown in Figure 1 of the drawings, in thenormal position of the slides or gate sections 18 and19 the same overlap and thus completely close the water passageway or opening 17.

It is obvious from thecons'truction so far that the lower slide or gate section 19 can be elevated, leaving the upper gate section or slide 18 in its normal position, which will allow the water to flow under the gate sections. The upper gate section can be lowered leaving the lower gate sectionin its normal position so as to permit the water to flow over the top of the gate sections when desired. I

prefer to provide a stop 21, or rest for the lower edge of the bottom gate section 19 and this may constitute a strip of metal extending across one ,face of the plate having its terminals anchored in the inner guide 12, as shown. The lower edge of the stop plate 21 is secured rigidly to the face of the body plate in any preferred wav. such as bv solder or the like and flared slightly outwardly from the face of the plate to facilitate the insertion ofthe lower edge of the lower gate section between thestopplate and the face of said bodv plate.

The outerguides 13 receive the tail p ece 25', which can be substantially 'U-shaned in cross section. The inner edge of this tail piece is nrovided with inwardlv directed laterally disposed guide flanges 26. which are slidably received in the outer guides 13 and the shoulders 13' will hold the flanges 26 against accidental lateral displacement from the outer guides 13. Thus this tail-piece can be raised or lowered in-th-e outer guide to correctly position the same relative to the bed of thestream. When it isdesired' to secure the tail pieceagainst movement suitable bolts 27 can be employed which can be passed through the body plate 10 and through the stop plate 21, if so desired.

It is. obviousjfrom thev foregoing that an exceptionally simple and durable head gate has been provided embodying a minimum number of parts which can be placed upon the market atan extremely low cost.

v "I can utilize a single slide gate 28 in lieu of the upper and lower gate sections 18 and 7 19, and I haveshown this gate in Figure 6 of the drawings. In this instanceboth the gatesil8 and 19 are removed from their guides and a shingle gate 28 substitutedtherefor.

In certain instances, where piping or the 7 like is used for conveying the water proallel inner and outer guides for-ming'means .for reinforcing the plate, a slide gate slidably mounted in the inner guides, a U-shaped tailpiece having laterally and inwardly direced guide flanges slidably received in the outer guides, said outer guides being "off-setwith respect to the body plate andlhavingshoulders upon the'outer longitudinal edges of said outer guides for holding said flangesof said tail-piece against accidental lateral displacement, and said body plate provided witha water opening formed inthe plate between the guides. In testimony whereof I aflix my signature.
